Trying to breathe some life into a near-moribund Kunena Forum on my site, I tried to add a topic to a new category I'd defined today. The Preview button works as expected but the Submit button (has a tooltip for and) opens the dialog to upload an attachment. This is such an obvious error that it must have something to do with my configuration or install (just installed a fresh download a few minutes ago - no joy). I would appreciate any help with this.

History - Imported the posts that were in PHPbb about three years ago, all looked OK. Upgraded from Joomla 2.5 to 3.0 in February of this year, now running Joomla 3.4.1. All looks well. Tried posting to an old category - same symptom. I'm logged in as a superuser. Others have posted since the February upgrade.

Thank you for your reply. What I have found is that the problem seems to be isolated to me only - others with comparable privileges use the Forum with no issues.

Also: the problem exists of Firefox and FF Developer Edition as I run it, and also is Safe Mode and in Private Browsing mode. It exists in Chrome as I run it, and in Chrome Private Browsing mode. It does NOT show up in MSIE version 11. That is, I can save posts in MSIE but nowhere else.

Probably unrelated but although I have enabled avatars site-wide, I can not see a way to set an avatar or a signature for my account.

I have taken all the steps you recommended except using SEO URLs, which I don't want to do. We don't care about SEO rankings. There is still no obvious way to attach an avatar to my profile.

Re unable to submit, I received another report from a user unable to submit today. He uses Safari on a Mac.

When I disabled the ability to upload images AND files, the Attachment prompt disappeared, and Submit works as expected. I suspect there is something in the image/file upload HTML or CSS that's causing the problem, but I don't want to delve into your system to try and isolate it.

If you want back-end access to my site to explore further, I will grant same vie email or PM.
